Description
Die Erfindung betrifft einen elektrischen Verbinder mit einem an einer Vorrichtung befestigten Kontaktelement, einem dazu passenden Gegenkontakt und einer Leiteinrichtung, die das Kontaktelement beim Zusammenfügen in die entsprechende Lage zum Gegenkontakt bringt.The invention relates to an electrical connector with a device attached contact element, a matching mating contact and one Guide device that the contact element when merging into the corresponding Position to the counter contact.
Elektrische Vorrichtungen, insbesondere Leiterplatten mit elektronischen Schaltungen, werden üblicherweise über Kabel, Leitungen und Drähte mit Sensoren, Aktuatoren und ähnlichen Vorrichtungen elektrisch leitend verbunden. Meist werden die Leitungen und Kabel, beispielsweise im Kraftfahrzeug, zu einem Kabelbaum zusammengefaßt. Dabei besteht der Nachteil, daß die Kabelleitungen lose innerhalb oder außerhalb eines Gehäuses verlegt sind, so daß der Kabelbaum sich, insbesondere beim nachträglichen Einbau, verklemmen kann. Andererseits bilden die frei verlaufenden Kabel eine große EMV-Strecke (Elektromagnetische Verträglichkeit) aus, so daß sich störende Signale in die Leitungen einkoppeln können.Electrical devices, in particular printed circuit boards with electronic ones Circuits are usually made using cables, wires and wires with sensors, Actuators and similar devices electrically connected. Mostly the lines and cables, for example in a motor vehicle, to a cable harness summarized. The disadvantage is that the cable lines are loose within or are laid outside of a housing so that the cable harness especially when retrofitted. On the other hand, make up the free running cables have a large EMC path (electromagnetic Compatibility) so that interfering signals couple into the lines can.
Zur Montageerleichterung sind elektrische Verbinder bekannt, beispielsweise Stecker und Buchsen, wobei durch Einführschrägen ein erleichtertes Finden beim Zusammenstecken erzielbar ist. Wenn die Stecker und Buchsen jedoch fest an den jeweiligen Vorrichtungen eingebaut bzw. befestigt sind, besteht der Nachteil, daß die Vorrichtungen so zueinander ausgerichtet sein müssen, daß der Stecker und die Buchse mit zueinander parallelen Längsachsen angeordnet sind. Das Ausrichten der Vorrichtungen in der entsprechenden Lage zueinander und das lagerichtige Zusammenfügen führt dabei zu erheblichem Kosten- und Personalaufwand bei der Produktion bspw. im Bereich der Automobiltechnik.Electrical connectors, for example plugs, are known to make assembly easier and bushings, with insertion bevels to make it easier to find Plugging together is achievable. However, if the plugs and sockets are firmly attached to the respective devices are installed or attached, there is the disadvantage that the Devices must be aligned so that the plug and the Socket are arranged with parallel longitudinal axes. Aligning the Devices in the appropriate position to each other and the correct position Merging leads to considerable costs and personnel expenses at Production, for example in the field of automotive technology.
Der Erfindung liegt daher die Aufgabe zugrunde, einen elektrischen Verbinder der eingangs genannten Art derart auszugestalten und weiterzubilden, daß sich das Kontaktelement und der dazu passende Gegenkontakt beim Zusammenfügen automatisch finden und dabei Lagetoleranzen zwischen Kontaktelement und Gegenkontakt ausgeglichen werden.The invention is therefore based on the object of an electrical connector to design and further develop the type mentioned at the outset such that the Contact element and the matching counter contact when joining automatically find and positional tolerances between contact element and Counter contact can be compensated.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Danach besteht das Kontaktelement zumindest abschnittsweise aus einem elastischen Material, so daß Lagetoleranzen zwischen dem Kontaktelement und dem Gegenkontakt ausgleichbar sind.This object is achieved by the features of claim 1. Thereafter, the contact element consists at least in sections of a elastic material, so that position tolerances between the contact element and the Counter contact can be compensated.

Das durch die Leiteinrichtung beim Zusammenfügen in die entsprechende Lage zum Gegenkontakt gebrachte Kontaktelement kann sich durch das elastische Material an die erforderliche Lage in Bezug zum Gegenkontakt anpassen. Dadurch kommt es zu einer erheblichen Montageerleichterung beim Einbauen, beispielsweise einer Leiterplatte in ein Gehäuse, wenn dabei das Kontaktelement mit dem passenden Gegenkontakt automatisch zusammengefügt wird. Da das Kontaktelement insbesondere starr mit der Vorrichtung, beispielsweise einer Leiterplatte, verbunden ist, ist auch kein Kabelbaum erforderlich. Deswegen werden Lagetoleranzen durch den elektrischen Verbinder automatisch ausgeglichen, ohne daß ein Kabelbaum vorhanden wäre, der sich zwischen mechanischen Bauelementen verklemmen könnte. Das Kontaktelement ist bevorzugt starr an der Vorrichtung, beispielsweise der Leiterplatte, befestigt. Das Kontaktelement selbst kann wegen des Aufbaus aus elastischem Material jedoch verformt und verbogen werden.According to the invention, it was recognized that position tolerances automatically compensate if the contact element at least in sections from an elastic material consists. This is done by the guide when assembling it into the corresponding one Position brought to the counter contact can by the elastic Adjust the material to the required position in relation to the counter contact. Thereby there is a considerable ease of assembly when installing, for example a circuit board in a housing when the contact element with the matching counter contact is automatically put together. Since that Contact element in particular rigid with the device, for example one PCB, is connected, no wiring harness is required either. That's why Positional tolerances are automatically compensated without using the electrical connector that there would be a wire harness between mechanical Components could jam. The contact element is preferably rigid on the Device, for example the circuit board, attached. The contact element itself can be deformed and bent due to the structure of elastic material become.

Der Grundkörper kann auch eine zusätzliche Schirmung aufweisen, so daß die elektromagnetische Verträglichkeit (EMV) des elektrischen Verbinders verbessert werden kann. Ein isolierender Grundkörper ist jedoch nicht zwingend erforderlich. Das elastische Kontaktelement könnte auch aus einem biegsamen aber leitenden Material, wie ein Federelement, hergestellt sein.The contact element preferably has an insulating base body, into which a electrical conductor is incorporated. In this way, the contact element can also as an insulating circuit board holder between the circuit board and another Device, for example an actuator or a sensor, can be used. The base body can also have additional shielding, so that the Improved electromagnetic compatibility (EMC) of the electrical connector can be. However, an insulating base body is not absolutely necessary. The elastic contact element could also consist of a flexible but conductive Material, such as a spring element.

Dies kann dadurch erfolgen, daß die Kontaktelemente als Abstandhalter zwischen zwei Vorrichtungen verwendet sind und die Vorrichtungen in ihrer Einbaulage die Kontaktelemente leicht in Richtung ihrer Längsachse zusammendrücken. Infolgedessen sind die Metallkontakte des Kontaktelements und des Gegenkontakts gegeneinander vorgespannt.The metal contact of the contact element can be biased against one Metal contact of the counter contact are pressed. This can be done that the contact elements are used as spacers between two devices are and the devices in their installed position the contact elements easily in Compress in the direction of their longitudinal axis.
